Wonderful work, congratulations!
: Here are a few images of the etched brass
: Finnieston Crane from Clydeside.
: This is a well-engineered kit of 'slot and
: tab' construction. On 'dry runs' the various
: parts all lined up with tab slots and holes.
: No glue of any kind is needed - except where
: you make a mistake - see below!
: This was my first time with an etched kit
: and I used only simple tools to fold up and
: close the tabs on the parts. I used 2 steel
: rules - one a heavy 1 inch wide one and the
: other a lighter weight 1/2 inch wide one. I
: also used a sharp scalpel, various types of
: tweezers, a fine file and a pair of
: flat-faced pliers.
: I cut the parts off the etch as I needed
: them. They were secured by tiny tags.
: Sometimes it was possible to trim off the
: tag completely, other times I had to run the
: file over whatever was left sticking out to
: remove it.
: Folding the main parts was straightforward -
: I held the piece at the fold line with end
: of the heavy steel rule and folded it by
: inserting the lighter one under the edge to
: be folded. Access to some folds was tricky
: and this is where a combination of tweezers,
: scalpel and pliers needed to be used.
: Cutting and folding were the easiest part of
: the job. Assembling the pieces so they
: didn't distort or bend permanently was where
: assembly became a 'challenge'.
: I don't know the thickness of the brass
: sheet used, but it is thin and the parts all
: bend easily. Getting purchase to fold the
: tabs was difficult at times but with
: patience I managed this. Getting the fold
: correct was also a challenge. The
: instructions are nicely drawn, but small in
: size and a few views of the assembled model
: would have been a great help in getting the
: fit right first time. Etched brass usually
: only bends once if you try and bend it back
: the other way it will break.
: The only part of the build that I must have
: got wrong is the location of the cabin at
: the top of the access column. I bent it
: incorrectly and then had to super-glue it in
: place - and it is, consequently, too low.
: The pathways in the jib that the 'hoist
: mechanism' runs on distorted slightly when
: the whole jib was tabbed together. There are
: minute pins each side the pathways to locate
: on the jib sides - these line up when not
: under stress - with just a little distortion
: many of them do not line up with these
: location holes.
: I think I must have folded some of the tabs
: the wrong way as the jib does not rotate. It
: fouls on tabs, but it does move a few
: degrees from side to side.
: All in all this kit builds into a nice
: model. I think it would be easier to build
: if the brass was thicker and the
: instructions were made more clear. Compared
: to a white metal crane of this type it looks

: There are specialist etch folding tools
: available, but for a one-off build I didn't
: feel the cost was justified.
